We have two "Butterfly Bushes" in our front yard that can really attract some lovely butterflies. I enjoy seeing them from our front window fluttering about the two bushes ... who can dislike a butterfly?! Butterflies symbolize renewal due to their amazing transformation from a caterpillar/cocoon. In a similar vein, butterflies can also symbolize the Resurrection of Christ.
So whoever is in Christ is a new creation:
the old things have passed away;
behold, new things have come.
